Michelle Obama: Democrats' Secret Weapon?

It's time to bring out the big guns. Michelle Obama will do the most extensive campaigning she's done since she helped get her husband elected in 2008 and will hold rallies and fundraisers for seven candidates across the country over the next two weeks. The popular first lady's strategic tour will be across the midterm-election battleground states of Illinois, Colorado, Wisconsin, New York, Washington, Connecticut and California. According to polls, Obama is more popular than her husband nationwide. She really could be the Dems' midterm-election secret weapon.
